To lubricate the motor to prevent overheating and wear and tear on the engine
I'm assuming its a riding lawn mower of some type. Our own lawn mowers of this type have an alternator in them that keeps the battery charged
YES
Kilograms.
to make a lawn you can either buy turf (rolled up lawn) or buy lawn seed.
No, not all small engines use gravity feed fuel systems. While some small engines, like those found in lawn mowers and small generators, may utilize gravity feed, others rely on fuel pumps to deliver fuel, especially if they are designed for higher performance or have specific fuel delivery requirements. Fuel pumps can ensure a consistent flow of fuel regardless of the engine's orientation or fuel tank position. Thus, the type of fuel system depends on the engine design and intended application.
Two-cycle lawnmower engines are rare.
Lawn tractors have oil filters.push mowers don't. Change oil more frequanetly in a push mower engine.hope this helped. S.g.
Lawn mowers can take 2 stroke or 4 stroke oil depending on the type of engine. If unsure contact your lawn mower provider.
Most all riding mowers use SAE 30 oil.
Scythes.
generally a quality 30 weight
No. Do not use in your car. It is for use in some lawn mowers and aircompressor motors.
It can vary between 30W and 10W30. L-heads use 30W, OHVs often use 10W30.
Lawn mowers are not destroyed after a single use, and they retain usefulness for many years, so, yes, lawn mowers are durable goods.
The majority of lawn mowers are not robots. That is not to say that all lawn mowers are not robots. Some companies have been manufacturing robotic lawn mowers (Lawnbott, Norman, etc.)
Um... because they have an engine like your car that has moving parts and cylinders... only significantly smaller?
20-50 motor oil
